The Financial Crimes Enforcement Network (FinCEN), a bureau of the U.S. Treasury Department, has withdrawn a 2023 proposal that would have required financial institutions to report certain crypto-mixing transactions. The proposal was pulled before it ever took effect, meaning no new reporting requirements were imposed on crypto businesses or users.

The withdrawal means the proposed reporting requirements never became law and are no longer in the regulatory pipeline. The decision forms part of a broader shift in the U.S. government's posture toward crypto regulation, with the Treasury Department also moving to drop separate reporting rules that targeted wallets and mixers.

What the 2023 Crypto-Mixing Proposal Covered

Crypto mixing, sometimes called a “mixer” or “tumbler,” is a service that blends multiple users' cryptocurrency transactions together. The practice makes it harder to trace individual funds as they move across a public blockchain. That same obfuscation is what put mixers on regulators' radar: while many users turn to them for privacy, the obscured trail can also complicate efforts to detect illicit flows, a tension that defined the debate around the proposal. Under the 2023 proposal, FinCEN would have classified crypto mixing as a category of activity that financial institutions were required to flag and report to regulators.

The proposal was issued as a Notice of Proposed Rulemaking, which is the standard first step in the U.S. federal rulemaking process. That process invites public comment before any rule becomes binding — a stage where affected industries and advocates can push back, and where proposals can be revised or abandoned entirely. FinCEN's proposal never advanced past the comment stage, and no final rule was ever adopted.

Why FinCEN Withdrew the Proposal Before Implementation

According to reporting by CryptoSlate, backlash against the rule contributed to its demise. The proposal faced criticism from privacy advocates, crypto developers, and industry groups who argued it was overbroad and threatened legitimate privacy-preserving uses of blockchain technology.

With the withdrawal, the 2023 proposal is formally off the table. It will not be revised into a final rule in its current form, and any future attempt to regulate crypto mixing would require regulators to begin a new rulemaking process from scratch.

The move fits into a broader pullback in the U.S. crypto enforcement posture. The Treasury has separately moved to drop reporting rules targeting wallets and mixers more broadly, signaling a shift away from earlier, more aggressive proposals.

What This Means for Crypto Reporting Policy

For everyday crypto holders, the practical impact is straightforward: the reporting requirements described in the 2023 proposal do not exist. No financial institution is currently required to file special reports on transactions involving crypto mixing under the withdrawn rule.

For businesses operating in the crypto space, including exchanges and wallet providers, the withdrawal removes a compliance uncertainty that had been hanging over the industry since 2023. Crypto businesses still operate under existing Bank Secrecy Act obligations — the anti-money-laundering framework FinCEN itself administers — and other anti-money-laundering rules, which were not affected by the withdrawal.

Whether U.S. regulators will revisit crypto-mixing policy under a new framework remains an open question. The Commodity Futures Trading Commission (CFTC) has also been working to define a federally regulated path for crypto, and the broader shift in U.S. regulatory posture toward digital assets continues to evolve. For now, the 2023 FinCEN proposal is gone, and no replacement rule is currently in place.

For individuals who hold cryptocurrency or are considering a first purchase, the news does not require any immediate action. It simply means one proposed layer of financial surveillance did not move forward.
